I look forward to adding this K&N filter to my 2005 GMC (AWD) 1500it has a 5.3ltr Engine and is customized by WarSaw Co. out of IN.There's a wheel-chair lift and secure area within the van (for my wife). I'm Pleased with the change in performance and fuel mileage increase and the fact that it's possible to clean the filter(s) reapply the formulated oil by spray pump. This is a SAVINGs when properly maintained and the vehicle(s) are properly Tune-Up.
Thank You for the Creation of your product(s).
Sincerely
Fred D. Henrahan, III
